 high, its posterior extremity being on a line with the rostro-labial 

 suture ; feebly notched on its inferior margin. Nasals broader poste- 

 riorly than they are long. The third labial not in contact with the 

 nasal, and it is almost excluded from the orbit by the fourth labial and 

 prse-ocular. One post-ocular. The fifth and sixth labials transversely 

 divided. Two temporals, of which the anterior is the larger. Two
